18、llennia in the manufacture of surfactants, e.g. the first surfactant used by mankind, was already completely bio-based soap. With the advent of modern surfactants in the early 20th Century, petrochemical-based raw materials also became of interest. They offered the opportunity to tune the surfactant
19、 properties, in a broader sense, to their various applications. The last decades have seen the emergence of new bio-based raw materials for surfactants. Some of the reasons for the increased interest lie in the bio-based products potential benefits in relation to the depletion of fossil resources an
20、d climate change. Acknowledging the need for common standards for bio-based products, the European Commission issued Mandate M/4921), resulting in a series of standards developed by CEN/TC 411, with a focus on bio-based products other than food, feed and biomass for energy applications. The standard
21、s of CEN/TC 411 “Bio-based products” provide a common basis on the following aspects: common terminology2); bio-based content determination; Life Cycle Assessment (LCA)3); sustainability aspects4); declaration tools. It is important to understand what the term “bio-based product” covers and how it i
22、s being used. The term “bio-based” means “derived wholly or partly from biomass”. It is essential to characterize the amount of biomass contained in the product by, for instance, its (total) bio-based content or bio-based carbon content. The bio-based content of a product itself does not provide inf
23、ormation on its environmental impact or sustainability, which may be assessed through Life Cycle Inventory (LCI), LCA and sustainability criteria. In addition, transparent and unambiguous communication within bio-based value chains is facilitated by a harmonized framework for certification and decla
24、ration. Breaking down the horizontal standards to bio-based products like bio-based surfactants, the European Commission issued Mandate M/491, resulting in standards developed by CEN/TC 276. This Technical Specification has been developed with the aim to fulfil part of the Mandate to describe the te
25、chnical requirements of bio-based surfactants. The criteria for “bio-based surfactants” published in this Technical Specification are complementary to the horizontal standards by CEN/TC 411. Surfactants are products which have the ability to reduce interfacial/surface tension, wet surfaces, suspend
26、materials or emulsify oils and fats. In Europe, thousands of producers, manufacturers and 1) A mandate is a standardization task embedded in European trade laws. The M/492 Mandate is addressed to the European Standardization bodies, i.e. CEN, CENELEC and ETSI, for the development of horizontal Europ
27、ean Standards for bio-based products. The M/491 Mandate is addressed to the development of European Standards for bio-solvents and bio-surfactants. 2) EN 16575. 3) EN 16760. 4) EN 16751.

28、strial applications. The surfactant-producing industry is composed of mainly multinationals. Downstream users are found in multinationals as well as SMEs. Surfactants may be produced from both fossil and renewable carbon feedstock (ref. EN 16575 -vocabulary). The amount of crude oil used for surfact
29、ant production is, however, low with less than 1 % of the total worlds crude oil consumption. Finally, the approach for these Technical Reports/Specifications/Standards intends to strengthen and harmonize the reputation of “bio-based surfactants” and the confidence of the customer in this product gr

PD CEN/TS 17035:2017CEN/TS 17035:2017 (E) 6 1 Scope This Technical Specification sets requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It lays down the characteristics and details for assessment of bio-based surfactants as to whether t
31、hey: are fit for purpose in terms of performance related properties; comply with the requirements regarding the health, safety and environment which apply to general surfactants; are derived from a certain minimum percentage of biomass; and comply with at least similar sustainability criteria as com
32、parable (non-bio-based) surfactants. The criteria of the regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) 11 also apply to bio-based surfactants. NOTE EN 16575 defines the term “bio-based” as derived from biomass and clarifies that “bio-based” does not imply
33、 “biodegradable”. In addition, “biodegradable” does not necessarily imply the use of “bio-based” material. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

45、facial/surface tension, wet surfaces, suspend materials, or emulsify oils and fats. They make it possible to process, apply, clean or separate materials. Surfactants are widely used in consumer and professional products and for industrial applications. Surfactants are typically used on their own or
46、in combination with other surfactants and other agents to fulfil the requirements of the respective applications. Examples of applications for surfactants are: cleaning agent; foaming/defoaming agent; wetting agent; emulsifier; viscosity modifier; surface tension reducer; process aid; fabric softene

This section gives a common set of technical properties characterizing the performance of surfactants including bio-based surfac

Due to the absence of international surfactant specification standards, it is necessary to provide to potential users the means to qualify the bio-based surfactant products, especially for its technical performance. Additionally, there are a number of other factors which will determine the acceptance of a surfactant such as the Health, Safety and Environmental properties which are treated in another section of this document. Surfactants are used in such a wide variety of applications that it is not convenient to eva
